Abstract

L'invention concerne des configurations améliorées pour un transfert d'énergie sans fil. L'invention concerne des procédés et des conceptions pour des dispositifs et éléments électroniques implantables. Un transfert d'énergie sans fil est utilisé pour éliminer les cordons et câbles d'alimentation perforant la peau pour alimenter un dispositif implantable. Des résonateurs répéteurs sont employés pour améliorer les caractéristiques de transfert d'énergie entre la source et les résonateurs du dispositif.
